Crabgrass

Crabgrass, a weed grass commonly found in lawns. Few weeds are more difficult to kill. Crabgrass sends out jointed stems along the ground; these take root and produce new plants. The long flowering stalk has fingerlike spikes. Crabgrass is killed by hand weeding or by treatment with a spray containing sulfate of iron. Certain herbicides will prevent the seeds from germinating if applied to the lawn in the early spring.
